Assuming 1940 rear ends/axles are the same as 39, I had identical problem? At first I thought I was leaking brake fluid but it was one of the axle seals. I was hating the thought of pulling the axles until I spoke to a 40 expert who said he had a few after market slip on seals that do a good job of sealing the rear end w/o 'major surgery'. This was a very common problem showing up in the 50's already. We are talking about a aftermarket seal that is no longer available as far as I know. Mr friend gave me two and I subsequently located some at an old Ford parts store. Go ahead and email if you like as I might be able to help you. No leak in two years.
